LAWN-SPRINKLER.

A SPECIFICATION forming part of Letters Patent No. 437,118, datedSeptember 23, 1890.

Application filed May 17, 1890. Serial No. 352,127. (No model.)

To aZZ whom it may concern:

Be it known that I, DENNIS A. HoYr, a citizen of the United States,residing at St. Cloud, in the county of Stearns, State of Minnesota,have invented certain new and useful Improvemen ts in Lawn-Sprinklers,of which the following is a specification, reference being had thereinto the accompanying drawings.

My invention relates to portable sprinklers of that class known asrevolving sprinklers, in which the water issuing from the nozzle isuniformly distributed at a distance therefrom upon a large surface; andthe objects of my invention are to produce a sprinkler of attractiveappearance in which the direction and force of the current can beregulated. I attain these objects by the construction illustrated in theaccompanying drawings, in which-- Figure 1 is a perspective View of asprinkler constructed in accordance with my invention with a pivotedsprayer thereon. Fig. 2 is a side View of the same with amodifiedsprayer vin posit-ion. Fig. 3 is a transverse vertical sectionof a portion of the circular sprayer, illustrating its construction.Fig. Li is a transverse vertical section of a portion of the device,showing a spraydeiiecting plate attached thereto. Fig. 5 is an enlargedView of the pivoted sprayer.

In said drawings, A represents a circular plate provided with divergingsockets a on the under side thereof to receive one end of the legs B, ofsuitable length, and form therewith a tripod for the support of theoperating parts. In the center of the plate A is formed integraltherewith or attached thereto a tubular boxing a2, provided at its topand also at its bottom with suitable well-known means for connectionwith a hose-coupling cZ. The upper coupling forms a part'of the ilexiblerubber nozzle D. The lower coupling d forms a part of the flexible hoseO, through which the water is conducted to the apparatus.

At a suitable distance above the plate A a Iiat ring E is supported uponbent rods e, which have their upper ends inserted into said ring andtheir lower ends inserted into the plate A. This ring has a lateralextension which forms a bushing e2 to receive a shaft f, which carrieson its outer end a water-wheel F, of any suitable construction, and onits inner end a pinion f2, which is received in a groove in the top ofthe ring E. Said ring is also provided with three upwardly-projectinglugs e3, Veach having a stud projecting outwardly therefrom, upon whichthere is mounted a roller e4, and upon said rollers there is placed aflat ring G, having adjacent to its periphery a series of pendent teethadapted to mesh with the pinion f2 and be rotated thereby.

To retain the nozzleD adj ustably connected with the rotary ring G, anupwardly-bent wire g has its ends securedupon diametrically-oppositesides of said ring, and said wire is provided with a series of loops g3,into either one of which the metal tip D2 of the nozzle can be inserted,and the desired stream of water to issue from said tip is regulated by acock d2.

To revolve the water-wheel, a small stream of water is directed by apipe lo to a point preferably above the wheel F, but nearly tangentialthereto, so that in the escape it will impinge against or lill thebuckets or paddles of said wheel. The lower end of the pipe 7a isinserted within the tubular boxing a2, and its upper. end is providedwith a How-regulating cock 7a2.

To break into spray the jet of Water issuing from the tip of the nozzle,a wire sprayer L is placed upon and secured to the rotary ring G by itssupport L2, the latter consisting, preferably, of Wire bent to forlneyes Z to receive the ends of shaft Z2, to which are secured in anysuitable manner a series of metal strips or wires Z3, arranged thereonparallel to each other. The ends of the supporting-wire L2 can beinserted in perforations in the top of the ring G, or can have feet Z4to clasp said ring. The middle portion of the wire L2 is bent to Aformaloop Z5, of preferably rectangular form, within which the sprayer canrevolve under the impulse of a jet of water issuing from the nozzle. Aprop for the middle portion of the loop Z5 is obtained either bytwisting together the wires constituting an extension of said loop or bysecuring to the center of said loop a rod or wire Z, having its lowerend doubled over to enter and be retained in one of the loops g3 of thenozzle-guide g. To the bottom of the loop Z5 there is also pivoted ahook ZT, which has its lower end adapted to enter another of the loopsg3.

In place of having a Wire sprayer revolving in front of the jet of thenozzle, the arrangement Of these parts may be reversed and the `wiresprayer be retained stationary While the nozzle revolves therein, andthe jet of waterissuing from said nozzle will be converted into spray bycontact with the wires. In this case a Wire sprayeror deiiector Misplaced upon and secured to the stationary ring E of the frame. Saiddeector consists Of a series of metal strips or Wires m, having theirlower ends secured at any desired angle into a ring m2 and their upperends preferably secured together by ring m". The location of saidsprayer and of its lower end is such as not to interfere with therevolutions of the cogged ring E Vor of the nozzle therein, theelasticity of the rubber nozzle permitting it to revolve with said ring.

To protect a path or Walk, a house, or any other Object from the jet orspray Of water during a portion Of the rotation of thenozzle, aSheet-metal shield or deiiector N is secured to the stationary ring E,and the tripod is so located as to have its shielded side toward theobject to be protected. Said shield is preferably in the form of asegment of a cylinder with its upper portion bent inwardly at ot toproperly deflect downwardly the jet or spray of Water, as said shieldcan be used On the device either in connection with the Wire sprayer orindependently thereof.

Having now fully described my invention, I claim- 1. A lawn-sprinklerconsisting of a tripodframe having bent rods e divergent therefrom, aring E, secured to said rods and having rollers e4, a cogged ring G, apinion meshing with said ring, and a water-wheel upon the shaft Of saidpinion, With a tubular boxing secured in the top of the tripod-frame, ailexible nozzle coupled to the upper end of said boxing, a hose to thelower end, and a tube k, inserted in its sides, substantiallyasdescribed.

2. In a lawn-sprinkler, the combination of its frame, a rotary nozzleand nozzle-carrier, and a sprayer consisting of a series of wires unitedtogether and located in front of the end of the nozzle and its carrier,substantially as described.

In alaWn-sprinkler, the combination of its frame, a rotary nozzle andnozzle-carrier, and a sprayer mounted upon the nozzle-carrier andconsisting of a Series of Wires united together and mounted upon arotatable shaft and located in front of the end of the nozzle,substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
